Hydreigon

Carlita used her Hydreigon in her battle against Cilan's Pansage in the Harvest Battle Tournament. It managed to defeat him with one powerful DragonBreath. Upon seeing how powerful Ash's Tepig had performed in the Eindoak Town Harvest Festival Tournament, Carlita suspected that Tepig had been unknowingly powered up by Victini and requested a battle against him. Ash agreed, and used Scraggy to battle Carlita's Hydreigon. Although Hydreigon should have easily outmatched Scraggy due to the fact he was relatively young and inexperienced, another power-up by Victini allowed Scraggy to defeat Hydreigon with a single Headbutt. Carlita later used Hydreigon to help her and Iris (who had admired Hydreigon due to it being a Dragon-type) escape the collapsing castle.

In Victini and Zekrom, Hydreigon is Shiny. In Victini and Reshiram, it is normal colored.

Pokémon

Hydreigon

Hydreigon was Carlita's choice in the Eindoak Town Harvest Festival Tournament. It went up against Ash's Scraggy and was proven to be stronger as it was a fully evolved Pokémon. However, Hydreigon was subdued by Scraggy's Headbutt after Scraggy got a power up from Victini.
